I used the Omni website to request a quote for replacing seven radiators, adding one new radiator in a bathroom with no existing heating/plumbing, all with TRVs, an extra TRV for a radiator we were keeping, new kitchen tap and two bathroom taps replaced, boiler service and investigate a minor leak. Andy responded within a couple of hours, visited on the eleventh of January to assess work and quoted on the sixteenth. I agreed the quote on the eleventh of February as it was by far the most competitive. I was flexible on date, with no urgency. The work started on the fifth of April and completed over a few days at mutual convenience by the fourteenth of April. Unrelated to this initial work our toilet broke and so we asked Andy to install a new one we would purchase. He advised on the style we could choose due to awkward waste pipes. We also decided to add another radiator, and Andy adapted by preparing the plumbing in advance of the radiator being delivered so it would be an easier install. On initial completion of all work two of the taps required tightening, and Andy came out quickly to resolve, with no further issues. He also adjusted some floorboards for free. All work was clean and tidy. Andy's primary work is Gas and Central Heating plumbing, so we were grateful he was flexible to do the taps and toilet as well. Andy was friendly, balanced his work with personal/family commitments, and kept me informed of arrival times via text/WhatsApp or email throughout. Sometimes I had to chase, but nothing inconvenient. Overall solid professional job.
